Drain and slice the 400 grams firm tofu into 5 slices. Place the tofu on a wire rack and drain it for at least 30 minutes. If you want to get this started in the morning, be sure to refrigerate the tofu as it drains.

Heat a frying pan over medium heat and add the 2 tablespoons vegetable oil. Place the tofu in the pan with space between them, so they don't stick together. Pan-fry the tofu until it's browned on one side (3-4 minutes).
2 tablespoons vegetable oil
Flip the tofu over and brown the second side (another 3-4 minutes).
Use paper towels to wipe out any excess oil from the pan.
Add the teriyaki sauce and glaze the tofu, flipping them over repeatedly until the sauce has thickened and formed a thick glaze around it.
