Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Slice the tempeh into thin strips and cut the zucchini and red bell pepper into long, flat ribbons.
In a bowl, toss the tempeh strips, zucchini, and bell peppers with olive oil, smoked paprika, sea salt, and black pepper until evenly coated.
Spread the tempeh and vegetables in a single layer on the prepared baking sheet.
Roast for 18-20 minutes, flipping the tempeh halfway through, until the vegetables are tender and the tempeh is golden brown.
While the vegetables roast, lightly toast the two slices of sprouted grain bread.
Spread the hummus generously over both slices of the toasted bread.
Layer the roasted tempeh and vegetables onto one slice of bread, then top with the second slice.
Press down gently, slice in half, and serve immediately.
