Gradually stir in the flour and soy sauce into the water. The consistency should be a little thick (add flour if necessary). Season well with pepper and salt. Cut the tofu into slices and pat lightly. The thinner the slices, the firmer the schnitzel will be later, I cut them about 1 cm thick. Pour the liquid into a deep plate (e.g. soup plate) and place breadcrumbs on a second, flat plate. The tofu slices are now first turned in the liquid and then rolled in the breadcrumbs.
Heat the oil in the pan. Fry the schnitzel in it on both sides until golden brown. Serve with lemon wedges, which can then be squeezed out over the schnitzel.
Very cheap and easy to prepare, tastes great with all side dishes.
