Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Press the extra firm tofu with a heavy object for 10 minutes to remove excess moisture, then cut into bite-sized cubes.
In a large bowl, combine the tofu cubes, broccoli florets, and chickpeas, then toss with olive oil, sea salt, black pepper, garlic powder, and smoked paprika.
Spread the seasoned mixture in a single layer on the prepared baking sheet and roast for 25 minutes, flipping halfway through, until the tofu is golden and the broccoli is tender.
While the vegetables roast, whisk together the nutritional yeast, tahini, lemon juice, and water in a small bowl until the dressing reaches a smooth, pourable consistency.
Assemble the bowl by layering the roasted tofu and vegetables, then finish with a sprinkle of hemp seeds and a generous drizzle of the tahini dressing.
