Removing SMD parts more complex than a resistor or SOT-23 can be a real bear. You want to get the part off without damaging traces, and if possible, without damaging the part either. You could haul out your hot air tool or you could go in surgically with this handy SMD Removal Kit from Chipquik - SMD removal is made easy! It uses a special metal alloy that bonds to your solder but stays liquid for a long time so can melt it over the existing pads and then remove with tweezers. This version has a leaded alloy, best for use with lead-based solder.
