Bring about 3 cups lightly salted water to a boil in a medium-sized pot. Add pasta and cook, stirring occasionally, until tender yet firm to the bite, about 11 minutes.
Meanwhile, heat olive oil over medium heat in a large skillet. Add marinara sauce and diced tomatoes and stir. Add soy chorizo and mix until texture is even, 3 to 5 minutes. Add oregano, cayenne pepper, and paprika; reduce heat and simmer until pasta has finished cooking, about 8 minutes more. Add basil.
Drain cooked pasta; top with sauce. Season with black pepper and salt.
