This sounds like a class made of the Hengeyokai from oriental adventures, also I'd look up the feats for druid that allow humanoid bonuses for wildshape ability if you've ever turned into a specific animal type, like scent ability.
Speaking of scent, I'm surprised you don't have scent, track and other sensory abilities unlocked without being in animal form, that's totally what I think of when I think shapechanger or embodiment.
