Steve,
For such packages, I usually just expand the copper area around the device on both the top and bottom layers.  I then interconnect them with lots of large vias.  Effectively building a heat sink into the board.

  Subject: [AVR-Chat] d2pak heat sink


    
  I've been checking out the various heat sinks for D2PAK devices and confess
  to being confused as to how they are mounted. I'd also like some
  recommendations, if anybody has any, for ones that are the easiest to use.
  I need to be able to hand solder things.

  Thanks, Steve
