I pulled down the wildshape templates, and I can't say I really liked it, so I did my own implementation. I did it as a conferred Ability Bonus that you can turn on and off. This seems to work for me, and it gives you all of the animal forms Ex abilities as well(scent, low light, pounce, grab, etc). Right now I just have this one, but from here it should be easy to duplicate this for other animal and elemental forms.
