Add mashed tofu. Cut bread into crouton size pieces and quick fry in remaining oil with remaining tamari, garlic powder and nutritional yeast. Add to tofu mixture. Add remaining ingredients. Mix well. Place in a well oiled casserole dish and press down very well. Bake at 350 degrees F for 35 minutes. Allow to cool slightly, then turn out on a plate. Slice and serve. This is also excellent cold.
