So you have some dir and 2 files there: "my-shell-script" and
"guix.scm", right? If you don't care about shebang (I mean if you have
"#!/bin/sh" in the script, it will not be changed to
/gnu/store/.../bash), then you can use trivial-build-system. So the
contents of "guix.scm" can be:

(use-modules
(guix gexp)
(guix packages)
(guix build-system trivial))
(let ((script-name "my-shell-script"))
(package
(name script-name)
(version "0.1")
(source (local-file (string-append (dirname (current-filename))
"/" script-name)))
(build-system trivial-build-system)
(arguments
`(#:modules ((guix build utils))
#:builder
(begin
(use-modules (guix build utils))
(let* ((bin-dir (string-append %output "/bin"))
(bin-file (string-append bin-dir "/" ,script-name)))
(mkdir-p bin-dir)
(copy-file (assoc-ref %build-inputs "source") bin-file)
(chmod bin-file #o555)))))
(home-page #f)

Use "guix build -f .../guix.scm" to build it.
If you care about shebang, I think you need to use gnu-build-system
(there is a phase that patches shebangs), but it requires removing many
phases and probably some additional tweaking.
