Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu with a heavy object for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a medium bowl, whisk together the tamari and toasted sesame oil, then toss the tofu cubes in the mixture until coated.
Sprinkle the nutritional yeast, sea salt, and black pepper over the tofu and toss again until the cubes are evenly crusted.
Spread the tofu in a single layer on the baking sheet and bake for 25-30 minutes, flipping halfway through, until golden and crisp.
While the tofu bakes, whisk together the Greek yogurt, lime juice, garlic powder, and sriracha in a small bowl to create the zesty dressing.
Assemble the bowl by layering the fresh baby spinach, warm cooked quinoa, and steamed edamame.
Top the bowl with the crispy tofu cubes and finish with a generous drizzle of the zesty yogurt sauce.
