Traditionally Luau aka Kalua pork whether it was cut up or a whole hog was very simple, first the meat was rubbed liberally with Hawaiian red clay salt, called Alaea salt, wrapped in banana leaves and then slow cooked in an airtight, rock lined pit using hardwood very similar to mesquite.
This process heavily infuses the meat with a very deep, rich smokey and moderately salty flavor.
Now that is the traditional way before pineapples and other things were imported into the islands.
Nowadays all sorts of things get added to the pork, pineapple, ginger, coconut milk, etc, etc.
The deep rich smokiness is very hard to recreate in a standard smoker, the smoke just doesn't permeate through the banana leaves like it does in the pit.
Most Hawaiians and other people will recreate the smokiness using a generous amount of liquid smoke.
As for the banana leaves which I take the time to source, others use foil or unwaxed butcher paper , or even a slow cooker (gasp!) which yield similar results, but without the subtle flavor of the banana leaves
