In a bowl, mix the turkey, eggs, mushrooms, bread crumbs, soup mix, 1/3 cup creamy tomato soup, 2 tablespoons ketchup, 2 tablespoons barbeque sauce, and 1 tablespoon Worcestershire sauce. Mold the mixture into a loaf shape, and place in a baking dish. Sprinkle with chili powder.
In a separate bowl, mix the remaining creamy tomato soup, remaining ketchup, remaining barbeque sauce, and remaining Worcestershire sauce. Set aside.
Bake loaf 45 minutes in the preheated oven. Top with the sauce, and continue baking 15 minutes, to a minimum internal temperature of 165 degrees F (74 degrees C).
