Rituals and procedure to do hawan with ved mantras is actually taught in person. So, you are advised to please make contact with local nearest Arya Samaj mandir, where Purohit will sure teach you.

I also paste my article below:-

HOW TO DO HAVAN

Please sit in the morning to perform havan. Havan must be in sunlight then it is more beneficial. Then half a bowl of fresh water with a tablespoon must be with you with small twigs especially of mango tree if possible, havan samagri, ghee, camphor and match box must be there with you. Please sit on sukh asan on four times folded blanket and blanket must be on mat.

Sukh asan i.e., sit on duly folded feet in comfortable position. Then first close your eyes and concentrate between two eyebrows and chant Gayatri mantra three times within heart and not by mouth. Then open your eyes.

Take one spoon of water in right palm. Chant this mantra, OM AMRITO UPASTRANMASI SWAHA and drink the water which you have put in your palm. Then again take the spoon of water in right palm then chant the next mantra, OM AMRITA APIDHANMASI SWAHA, and drink the water. Then again take the water in right palm and chant the mantra, OM SATYAM YASHAH SHRI MAYI SHRI SHRAYTAAM SWAHA, and drink the water. Then wash the right palm while sitting, with the same water kept in bowl.

Then put the twigs into havan kund with one piece of camphor and burn it. During this process chant the Gayatri mantra again and again till such time the fire is lighted sufficiently. Then chant the Gayatri mantra and at the last add the word Swaha and offer ghee with tablespoon, quantity equivalent to 4 to 5 drops. And if you are alone then also offer in fire pinch of havan samagri from your right hand’s finger and thumb avoiding forefinger. So this offering may be of 11 times, 21 times or 51 times as the time suits. It is the simplest way and I have not quoted the complete method of Yajna. The havan with Ved mantras are always offered as the best worship of God only please. Do havan daily and both times.

Besides, I’ve written a book – Yajyen Karma Sarvashreshth Ishwar Pooja worth Rs. 65/- excluding postal charges, in which procedure to do hawan is described .The book can be sent to you on receipt of your postal address, if you desire. Moreover VCD showing how to do havan is also available, if you desire. For the ved mantras required by you, one has to sit before acharya to learn. So, either you come here or make contact with local arya Samaj Purohit.

Jai: Is Krishna God?
Swami Ram Swarup: According to Vedas, avtarwad does not exist.

Avtar

God is only one who creates the universe and no other can create the universe except God. Please think deeply is any one except God empowered for creation, etc.? The pious qualities of God are unlimited whereas qualities of soul, which resides in human body, are limited. That is why He is God. This fact is also mentioned by Rishi Patanjali in his Yog shastra sutra 1/24, “KALEASHKARAMVIPAKASHYAIHI APRAMRISHTAHA PURUSHVISHESHAHA ISHWARAHA” i.e., He who is not indulged in any sorrows/sufferings (kalesh), in any kind of deed (karma) and result thereof (vipakya), He is supreme in souls and is called Ishwar (God), whereas, soul is indulged in all the said matters according to deeds done in previous, and in the present life. So this is also a difference between God and souls and therefore soul can never be God based on the different qualities.

Amongst unlimited qualities of God, few may be enumerated-that God creates, nurses and destroys the universe. God is omnipresent, omniscient and omnipotent and Almighty, beyond description, beyond imagination, and beyond calculation. Nobody on the earth can deny such qualities, but these qualities are to be discussed and considered deeply and he who does the same is called MUNI as per Vedas and shastras.

Let us think over one quality of God – Being Almighty. Almighty means God has all powers and thus God, to control the universe and to do any kind of deed for the same, can not be dependent on another, at any cost, being Almighty. Again shastras say, which is a true saying too, that there must be reason behind for any creation, matter etc. God is a reason to create the universe. Parents are the reason to give birth to a child. Ravana took Sita forcefully which became a reason for war between Shri Ram and Ravana etc. So as per Vedas there must be a reason of avtar and after studying eternal knowledge of Vedas and thinking deeply, there seems no reason to take avtar by Almighty God. As in Yajurveda mantra 2/26, so is in Shwetashwataropnishad shlok 6/8 wherein it is mentioned that there is no reason to form a God and thus God is also formless i.e., nobody can make God but God creates universe from non-alive prakriti. Secondly the said Upnishad says that the deeds of God of creation, nursing, and destruction of universe are eternal, natural, and automatic. So naturally God needs no avtar to destroy Kalyug, earth, or devils etc., being Almighty i.e., God has all powers and is independent. Not God but only His powers are enough to control, create, nurse, destroy the universe. That is why Upnishad says that God has no desire to create etc., but it is eternal and natural and this sort of desire is named “IKSHAN” and not desire to create etc.

Suppose God has to kill a devil and He takes avtar and God kills the devils by arrow etc. It means God is not Almighty and independent because God has taken help of Avtar (Human body) and arrow, gun, etc., which is impossible.

This all I have told based on fundamental law of eternal knowledge of four Vedas. Yet if anybody says about avtar then it is their own views and they are satisfied with their views and can not be commented because they could have been realizing at their own but so far as eternal knowledge of Vedas is concerned, Avtar is not possible.

Jai: Swami you say god has no avtaras and god takes avatars only for reasons, you also said that god has no reason to take avatars , but god who is all mighty can take avatars to teach people about dharma
Swami Ram Swarup: I do not say anything but previous as well as present rishis along with me, preach the vedic philosophy. So, whatever I tell are the eternal vedic views.

There remains no reason for which God needs to take avtar. Moreover, if God takes avtar then he will have to come out of all the matters of universe which is not possible. Amongst unlimited divine nature and qualities of God, it is also His nature to be Omnipresent. If He takes avtar then this eternal nature will be changed but according to Rigved mantra 3/56/1, God Himself states that His fundamentals are unchangeable and unchallengeable. So avtarwad is not possible.
