Line a large rimmed baking sheet with parchment paper.
Place the sweet potatoes on the prepared baking sheet. Add 2 teaspoons olive oil, smoked paprika, garlic powder, salt, and black pepper.
Toss the sweet potatoes until evenly coated. Spread the sweet potatoes in a single layer.
Roast for 25 to 30 minutes, turning halfway through, until tender and browned around the edges.
In the meantime, place the steak in a medium-sized mixing bowl. Add 1 teaspoon olive oil, chili powder, cumin, garlic powder, smoked paprika, salt, and black pepper. Toss until the steak is evenly coated.
Heat a large skillet over medium-high heat.
Add the steak to the skillet in a single layer.
Cook for 5 to 7 minutes, turning occasionally, until browned and cooked to your preferred doneness.
Remove the steak from the skillet. Let the steak rest for 5 minutes.
In a small mixing bowl, add the Greek yogurt, lime juice, water, garlic powder, cumin, and salt. Using a wire whisk, mix until smooth.
Divide the romaine lettuce between 4 bowls. Add the roasted sweet potatoes, steak, black beans, corn, tomatoes, cucumber, and red onion.
