Black Diablos armour is very good for Lao, as it has High Wind Res. Also, bringing Large Barrel Bombs and materials to make more of them is a good idea (blow them up next to his head when he enters each area). Farcasters are useful too, to avoid being "juggled" by his tail. Other than that, just use a powerful dragon/raw (fire might be okay too, I can't remember that well) weapon that you know how to use well, and hit him in the belly.
