Let the steaks come to room temperature for 20-30 minutes, then pat dry with paper towels.
Lightly season with salt, and rub them with Worcestershire sauce (you could also use olive oil or Dijon mustard), and set aside.
Combine the black pepper, garlic and onion powder, oregano, cumin, thyme, brown sugar, chili powder, and paprika in a large bowl or deep plate.
Thoroughly coat every inch of the steaks with the dry rub mixture, and let them soak in the flavor from the rub for 15-20 minutes.
Heat the smoker to 225°F (107°C).
Soak the wood chips in water for about 30 minutes, then drain them. For a smoker, add the wood chips to the smoker box.
To keep the meat moist and stabilize the smoker's internal temperature, fill a heat-proof pan with water and place it on the lower rack or the same rack as far as possible from the meat.
Place the pork steaks away from the direct heat.
Smoke the steaks for 1-1½ hours or until they have an internal temperature of at least 145°F (63°C). How long it takes will depend on the steak's thickness and your smoker's temperature.
Remove from the smoker and let them rest for 10-15 minutes to reabsorb the juiciness.
Brush with your choice of BBQ sauce if desired, and serve with your favorite sides.
If using the grill, set it up for indirect heat with the charcoal on one side. Then, use a smoker box or make a foil pouch with the chips inside and poke holes in it.
