Cook the pasta according to the package instructions. Drain the pasta and set aside to cool.
Add the oil to a large skillet and heat on medium heat. Add the drained corn and saute the corn for about 10 minutes, stirring occasionally, or until the corn is golden brown. Remove from heat and set aside to cool.
In a large bowl, whisk together the crema, Greek yogurt, smoked paprika, garlic powder, onion powder, salt, and lime juice. Fold in the cotija cheese, cilantro, red bell peppers, and green onions.
Once the pasta and corn are cool to the touch, fold them both into the pasta salad mixture, tossing well to coat. Garnish with more cilantro leaves, lime wedges, and/or cotija cheese. Serve!
