I found this at VegWeb.com:

Ingredients:
substitute for 2 eggs (mix 1 tablespoon arrowroot powder, 1 tablespoon corn starch, and 4 tablespoons water)
1 tablespoon soy sauce
1 box medium firm silken tofu (350 g)
3/4 cup chopped walnuts
1 packet vegan dried onion soup mix (1.5 oz)
1 teaspoon oil
1 1/2 cups chopped onion
2/4 cup chopped celery
2 cups chopped mushrooms (use portobello mushrooms for a heartier taste)
1 1/2 teaspoon each of oregano and basil
1/2 teaspoon sage
1 1/2 cups bread crumbs (Variations: To make it stick together better, try lowering the bread crumbs to 3/4 cup and adding one of the following: 1 extra box of tofu, 1 cup of instant mashed potato flakes, 1 - 1 1/2 cup of cooked brown rice or 1 cup burger-style crumbles)

Directions:

Mix egg substitute, soy sauce, tofu & onion soup mix together in blender. Add walnuts & blend until smooth.

Saute vegetables until onions are transparent (add other diced veggies if you wish - ie peppers, carrotsetc). Add herbs/spices while vegetables are frying.

Mix blender ingredients, cooked vegetables and bread crumbs together in a large bowl.

Press into a greased loaf pan. (Or, as user giraelei suggests, "Instead of a loaf pan, I usually use a square cake pan and liberally coat the loaf with ketchup so it gets kind of burnt and caramelized. Yum!")

Bake at 350 degrees F. for 1 hour and 15 minutes. Let cool slightly. Turn loaf out and slice.

This has become a standard dish at my parents house when all sorts of eating habits must be catered to. Even the most obstinate meat eaters love it. It is also excellent the next day cold on a sandwich with a bit of mustard.
