Drain the tofu and cut it into three slices lengthwise. Place tofu on a double layer of paper towels, cover with more towels. Gently press with your hands, to soak enough water out into the paper towels.
Return the tofu to the cutting board and cut each piece into about 10 cubes. Place the tofu in a medium bowl to marinade.
Mix and whisk the remaining ingredients well in a smaller bowl. Pour over the tofu and stir the tofu until all sides are well coated. Let it marinate at least 10 minutes. The longer you marinate it, the more flavorful it will be.
Place the tofu in a single layer in the basket (leaving any marinade behind) Air fry for about 6 minutes at 350F. Use a thin, flexible spatula to loosen the tofu and turn it. Return it to the air fryer and begin checking at 4 minutes to check if it looks golden and slightly darker at the edges but not overcooked or it will be tough.
Serve over bed of rice and your choice of veggies and garnish with chopped green onion.
