Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the tofu to remove excess moisture, then cut into 1/2-inch cubes.
Place the cubed tofu, rinsed chickpeas, and diced sweet potato on the baking sheet.
Drizzle with olive oil and sprinkle with sea salt, black pepper, garlic powder, and smoked paprika, tossing well to coat.
Roast for 25-30 minutes, flipping halfway through, until the sweet potatoes are tender and the tofu is golden.
In a small jar or bowl, whisk together the tahini and lemon juice, adding a teaspoon of warm water at a time until a pourable consistency is reached.
Assemble the bowl by placing fresh baby spinach at the base, topping with the roasted vegetable and tofu mixture.
Garnish with hemp seeds and drizzle the lemon-tahini dressing over the top before serving.
