Wrap tofu in 4 to 6 layers of paper towels and place on a plate. Place a second plate on top and balance a large can or jar in the center to add weight. Let sit for 30 minutes.
Preheat the oven to 375°F. Line a large baking sheet with parchment paper and lightly coat with spray oil.
Unwrap tofu, discarding paper towels, and cut lengthwise into 8 slices. Cut each slice into 4 equal triangles. In a large pie plate, stir together cornstarch and salt. Gently coat tofu triangles and shake off any excess coating. Arrange tofu in a single layer on the prepared baking sheet. Bake in the bottom third of the oven until crisp, 30 to 35 minutes.
