Say I am designing a DMT / OFDM system, how do I decide on the frequency spacing between the tones / carriers ?

You defer to people with doctorates in the required disciplines and let them decide
More seriously it depends on absolutely tons of stuff. How good you expect the transmitters and receivers to be, the media the signal is propagating through, the frequency range in use, etc.
This might help given I'm a cable guy - here're the physical layer specifications for DOCSIS 3.1 which uses OFDM - for obvious reasons given this is the actual specification the level of detail is very high, and as a bonus it's free.
