Easiest way is to get Great Combustion and upgrade to at least +10 on the Pyromancy Flame, or higher. It will take 3 shots to kill the tail at +10, 2 if it was upgraded to the evolved flame +0 and 1 hit if its +5 evolved or higher. Now wait behind his crystal and let him use a beam attack and then run behind, he will be stunned for about 7 or 8 seconds, plenty of time to get a few Great Combustions onto the Tail. Of course any Halberd or Greatsword will work as well but Seath is weak to fire so that is the fastest way.
