how to modify the contents of a TCP/IP packet before it is delivered? Can
this be done with ip helper api, can it be done with sockets? I can't seem
to find any documentation on how to modify packets before they are
delivered.

Seems like you need a proxy. Implement a listener, and a sender.
Then put whatever logic between the tow.
