I don't have any directions I can give you except perhaps to get involved with a monastery where they produce incense. Ask the monks or nuns if they can show you. Can I ask why you are interested? Is it just out of curiosity or do you intend making it yourself?
Personally, I have enough difficulty approaching the making of prosfora with a proper humble and prayerful attitude. I think I'd only go as far as producing my own charcoal powder for the burning of incense.
