FTDI chips are all SMT, so no luck there, but you do have some options.
If you want to roll your own circuit board, look at the FTDI chip-in-a-cable that the RBB
uses. I like the looks of it, but haven't managed to acquire one yet.
Sparkfun and others make a breakout board that has the SMT part on a little board with through-holes. The lilypad arduino variant uses something like this.
If you happen to be seriously into rocketry, you may have one lying around: the MiniAlt family of altimeters use an FTDI breakout board as a computer interface.NKC electronics
has a kit with the SMT parts already soldered.
NKC and Fundamental Logic
both offer RS232 variants that you can use with a standard USB/RS232 adapter (of course, you'll have to apply power to the board when going that route).
There are probably other solutions; these are what I can think of off the top of my head.
