In a small bowl, mix together salt, pepper, paprika, onion powder, and garlic powder.
Rub pork chops with olive oil on all sides. Season with spice mixture and rub on all sides.
Heat a skillet or grill to high heat. Sear the pork chops briefly on each side, just enough to form a slight crust.
Place seared pork chops on the smoker. Close the lid and smoke until the internal temperature of the pork reaches 145 degrees F, which will take approximately 90 minutes, but will depend on the thickness of your pork chop. Use an internal probe or thermometer for best results.
