@Zett activate will bring the app to the front whether it is open or not. So really, all you need to do is check if the app you're looking for is frontmost. If it is, you hide it. If it isn't, you activate it. Ideally this should work but I don't care enough anymore to test it.

set appName to "Mail"
set needsActivation to false
tell application "System Events"
  if frontmost of process appName then
    set visible of process appName to false
  else
    set needsActivation to true
  end if
end tell

if needsActivation then
  tell application appName to activate
end if
