In a food processor or high powered blender, add the mushrooms, broth, soy sauce, peanut butter, liquid smoke, Worcestershire sauce, tomato paste, and beet until pureed, approximately 1 minute. Pour the mushroom mixture into the wheat gluten mixture and stir until it turns into a light and stretchy dough. If the dough seems too wet, add a bit more vital wheat gluten until it becomes really stretchy. Spread it evenly in the greased pan and bake for 30 minutes.
