depends on if you can take away that tablespace for a while.
If you can, and you really truly want to remove the datafile:
export the data from that tablespace (either table by table or by user)
alter that tablespace offline and drop it
recreate the tablespace without that datafile
import the data you exported.
If you can't take that tablespace away, and you are willing to live with the
"vestige" datafile:
you can resize the datafile down to a trivial amount and just leave it
there.
