If you could use grub-install then it should have copied all the modules
to your EFI partition.
But if you moved the grub.efi or created it yourself then you need to
copy *.mod *.lst yourself to the place where grub.efi is.
Or in grub console check with `set' the prefix and change it if needed.
Maybe there's something useful for you in the GRUB wiki:

We added now to our Debian SVN trunk a grub-efi-ia32 package and
grub-efi-amd64 both avaible on i386 and amd64
