My theory is that Aang inadvertedly taught Ozai energy bending, who in turn taught it to Amon's ancestor.

Another Theory (More Plausible) is that Amon is either a spirit or is working for some evil spirits, who granted him his gift.

Amon could also be a bender of one of the four elements, and wants to be the only bender.
