Sorry, I missed you post.
Espeon and Glaceon need help with Steel types, so any IV spread that gives Hidden Powers Fighting, Fire, or Ground can work for them. HP Fighting is generally prefered on Espeon though, so it can hit Dark types harder.
Jolteon prefers HP Ice, but can also benefit from HP Grass. HP Grass should only be chosen if your team needs help versus Swampert, Gastrodon, or Quagsire. Electric/Ice combo is only resisted by Shedinja, so you will get great coverage.
