Can anyone give me an example config on how to PAT based on destination address?

Site A:
Cisco C2800 ISR
Public address:
VPN Peer

Site B:
Cisco Concentrator 3005
Public address:
VPN Peer

At site (A) I have a Cisco 2800 router with a VPN connection to site B.
On sites A's router, I need to configure PAT only when destined for host that is on the other side of the VPN tunnel. All traffic from network will be PATed to
All other traffic PAT's the same out their respective interface.

Any help would be much appreciated.
