For best results, press the tofu using a tofu press or heavy weight for a couple of hours, up to overnight.
Slice the tofu into ½ inch slices. Set aside.
Combine the ketchup, mustard, soy sauce and garlic powder in a small bowl. Stir until smooth.
Pour the sauce over the tofu slices and toss until all tofu is fully coated.
Line the tofu slices up on a baking sheet lined with parchment paper. Broil on high for five minutes. Flip each piece, then broil for an additional five minutes.
Serve hot.
