what I do is to have the external HDD encryption passphrase in a GnuPG
encrypted file of my main hard disk. Then, a bash script takes care of
(1) getting the passphrase from the encrypted file, (2) mount the
external disk with the passphrase. That way, you can use your smartcard.

All my passwords are in GnuPG encrypted files and handled by
https://www.passwordstore.org/.
