While I never tried in in TFT, one thing I have done in other games where I didn't want to add straight out clerical magic was to make whatever "useless" trait was required for priesthood equivalent to whatever trait was used for mundane healing but without the requirement of gear (e.g. you pray over the injured and lay hands on the wound and you can get the equivalent of First Aid without needing to have any bandages on you).

It's a sufficient benefit within the theme of what players tend to expect of fantasy clerics to make it at least marginally worthwhile, without actually forcing actively interventionist gods into the setting, and adapts easily enough to some different ability should you have gods around for whom healing isn't really appropriate.
