Preheat oven to 350 degrees F (175 degrees C).
In a bowl, mix the cream cheese, walnuts, onion, eggs, oats, and soy sauce. Form into patties.
Heat the oil in a skillet over medium heat, and cook the patties 2 minutes on each side, just until firm.
Place the patties in a baking dish. Pour in the cream of mushroom soup.
Bake 1 hour in the preheated oven.
