Perhaps you need assistance with the format more than anything. Otherwise I strongely suggest you just sit with your dad and capture his work history etc etc and use your own words.
Yes, it is a long and painful exercise. lol
Note: I am an IT guy and I work as an independent contractor. Over the years I have had my resume with a few agencies. Every single agency hates my resume in the beginning and then re-format it to their specification. Agency 1 reformats my resume and then awhile later I sign up with another agency and they hate the reformatted version. My point? There is no standard resume format that everybody will like.
Here is one format example.
