Making a delicious stir-fry shouldn't be hard. First, prep the tofu by wrapping the block in paper towels and putting it between two plates with something heavy, like a jar of sauce, on top. Leave it that way while you chop up your veggies, at least ten minutes, to get water out of it. Then cut it into 3/4" — 1" cubes. Next, heat oil in a wok or frying pan. Add your seasoning to the oil (sliced garlic and ginger are delicious). When it gets fragrant, add the tofu and cook for a few minutes on each side, searing it. Before you add the veggies, remove the tofu. Then, once your veggies are almost done, add the tofu back in and cook it all together for a couple of minutes.
