Place all ingredients in a large mixing bowl, in no particular order, and mix together with electric beaters.  If you'd rather, mix all ingredients in a blender.
The pudding will come out with a bit of a speckled appearance from the tofu and pumpkin, but I assure you this is very tasty.  I made it up about a half in hour ago, and if you can find where improvements need to be made, I'd love to hear them.  Since I had no whipped cream replacement readily on hand, I tossed some mixed nuts on top and it was very good.  I hope you enjoy it too !
