Wait a second, I see weaseling afoot!
If your original race granted you a nonspecific bonus feat (such as the one gained by a human at 1st level), any feat can be lost, so long as it is not a prerequisite for another feat you have.
If you no longer qualify for a feat due to the transformation, you lose the feat and immediately select a new feat for which you qualify in its place. You must also replace any feat for which the lost feat was a prerequisite.
I think you might be able to ditch vow of poverty (which isn't a prerequisite for the bonus feats it grants). Then you'd no longer qualify for those exalted bonus feats, and be able to switch them out of things that don't suck.
In-character justification:
"Dude, I'm serving a
dragon. It's now against my religion
not to assemble a hoard of treasure."
