Close grip bench
Skull crushers or over the head ez bar extensions
Bench Dips

I would usually start with skull crushers (making sure to warm up the elbows) because they isolate the tri’s more so that when I go on to Close Grip Bench or Dips, the tri’s are more stressed than the chest.

Whatever works for you, but you can’t go wrong with any of these three.
