Preheat oven to 350°F. Grease the bottom of a glass baking dish with 1 teaspoon of coconut oil. Open the package of tofu and drain water. Place block of tofu on a cutting board and gently pat it with a paper towel or dish towel until excess water is absorbed. With a sharp knife, cut the block in half length-wise then press again with paper towels to drain excess liquid. Cut blocks into 1 inch squares and place in a single layer in the prepared baking dish. Sprinkle soy sauce evenly on top.
