You can use the magic of rman tspitr as long as your tablespace is independent of other tablespaces:
There are 2 methods you could use with Data Pump.
1. tablespace mode export. expdp user/password tablespaces=<your list here> ...
2. transportable tablespace mode. expdp user/password transport_tablespaces=<your tablespace list here> ...
NOTE: for #2, you need to have your tablespaces in read only mode, then you need to copy the data files, and the
tablespaces need to be self contained.
Hope this helps.
