Most job centres can give you advice on what you can put on your CV, but I agree with the above poster, get out there and start getting some experience. One really easy thing to consider is something like how I volunteer at my local playgroup, we were going anyway and they needed people to help open and close, it's so little time out of my day to get there 10 mins earlier and leave 10 mins later to open and lock up and clean the cups.
