I have a very similar system to yours with the same partitioning scheme and formats. What I did was
1. Install the bootloader with: grub-install --target=x86_64-efi -- efi-directory=/boot --bootloader-id=GRUB 2. then generate the grub config with: grub-mkconfig -o /boot/grub/grub.cfg
Perhaps you can try this from chroot. You need to install grub and efibootmgr packages before running the above commands. Mind you, I'm a new Arch user :)
I did all this but ended up wher I was. So I ended up removing the kernel, grub and efibootmgr from a chroot, reformatted the EFI partion and re-instlled everything. Thi time grub- install and grub-mkconfig worked without any complaints and system is booting.
