The easiest way to do this is to add an action to your logHook that
checks the current workspace, and sets the keyboard layout if it is
the desired workspace:
 
  ...
  logHook = ...other stuff... >> checkKBLayout

  ...

  checkKBLayout :: X ()
  checkKBLayout = do
    curTag <- gets (W.currentTag . windowset)
    when (curTag == "foo") $ spawn "set keyboard layout"

Of course, "foo" should be replaced with whatever workspace you want,
and "set keyboard layout" should be replaced with a suitable command
for setting the keyboard layout.
