Press the tofu: place drained tofu on a paper towel–lined plate, cover with another towel and set a heavy pan on top for at least 10 minutes to press out excess water.
Make the marinade: in a small bowl, combine 2 tablespoons soy sauce and the grated garlic clove; whisk to combine.
Cut the tofu into cubes: transfer pressed tofu to a cutting board, halve lengthwise, then cut into 32 even cubes and arrange in a single layer in a medium shallow dish.
Season and marinate the tofu: sprinkle curry powder over the tofu and turn to coat. Pour the soy-garlic marinade over the cubes and flip to coat evenly. Marinate at least 10 minutes.
Make the peanut sauce: into the small bowl used for the marinade add the peanut butter, 1 teaspoon soy sauce, sriracha and 1 teaspoon grated ginger; whisk and add warm water a little at a time until pourable (about 2 1/2 tablespoons).
Air-fry the tofu: spray the air fryer basket with oil. Arrange tofu in a single layer and air fry at 370°F (188°C) for 12–14 minutes, shaking the basket halfway through, until golden and crisp.
Cook the cauliflower rice: while tofu cooks, heat a medium skillet over medium heat. Add 1 tablespoon olive oil, then minced garlic, 1 teaspoon grated ginger and the scallion whites; sauté about 30 seconds. Add riced cauliflower, sprinkle with 1/4 teaspoon kosher salt, and sauté 4–5 minutes, stirring often, until tender.
Toss tofu with peanut sauce: transfer air-fried tofu back to the shallow dish (or a bowl), pour the peanut sauce over it and toss to coat evenly.
Serve: divide cauliflower rice between two shallow bowls, top with half the tofu mixture, then sprinkle with scallion greens and chopped peanuts.
