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 10 minutes to remove excess moisture, then cut into 1-inch cubes.
In a large bowl, toss the tofu cubes, chickpeas, and broccoli florets with olive oil, sea salt, black pepper, garlic powder, and nutritional yeast until evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 20 to 25 minutes, flipping halfway through, until the tofu is golden and the chickpeas are slightly crisp.
While the vegetables roast, steam the shelled edamame in a small amount of water for 3 to 5 minutes until tender.
In a small jar, whisk together the tahini and lemon juice, adding a teaspoon of warm water at a time until a pourable consistency is reached.
Assemble the Buddha bowl by layering the roasted tofu and vegetable mixture over the steamed edamame, then finish with a sprinkle of hemp seeds and the tahini dressing.
