You can use the PKG() command in spec files to create a package. This is
documented, and you should be able to achieve that. You will want to use the
'DATA' typecode. Something like:
pkg = PKG([(fn, fn, 'DATA') for fn in glob("dir/*")])
After that, you can add the pkg to your EXE (add it to the toc using the 'PKG'
typecode).

I assume you're using single-file mode...

Well, it depends on why you're attaching those data files in the first place.
PyInstaller is not meant to replace MSI, InnoSetup, NSIS, RPM, DEB, or any
other packaging system of your choice. PyInstaller is meant to grab every
dependency which is strictly related to Python and third party libraries and
"put them together".
If your application uses external data files (like most applications out
there), just put them next to the executable, and ship everything together
with an installer. The support for data files is actually meant for third
party libraries using data files (and it's going to be enhanced with
pkg_resources API support as soon as I find time to work on it), or for those
rare cases where you really have just one or two data files and you don't want
to setup an installer just because of that.
