Combine lime juice, broth, soy sauce, olive oil, jalapeno, garlic, and paprika or liquid smoke in a large bowl. Whisk well. Add veggies and toss to combine. Cover and refrigerate for 30 minutes.
Heat vegetable oil in a large skillet over medium-high heat. Add veggies and cook, stirring occasionally, until veggies are softened and onion is translucent, about 5-7 minutes.
Heat tortillas in the microwave for 20 seconds. Remove veggies from heat.
Serve hot with toppings on the side.
