Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Drain the tofu and press it firmly between paper towels to remove excess moisture, then cut into 1/2-inch cubes.
Rinse and drain the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure they crisp up in the oven.
On the prepared baking sheet, toss the tofu cubes, chickpeas, and broccoli florets with the olive oil, smoked paprika, sea salt, and black pepper.
Spread the mixture in a single layer and roast for 20-25 minutes, tossing halfway through, until the tofu is golden and the broccoli is tender with charred edges.
While the vegetables roast, whisk together the Greek yogurt, lemon juice, and garlic powder in a small bowl until the sauce is smooth and creamy.
Place the warm cooked quinoa in the base of a serving bowl and top with the roasted tofu, chickpeas, and broccoli.
Drizzle the lemon-yogurt sauce generously over the bowl and serve immediately.
