I'm myself an overseas Brit, and looked into this myself a while back. Frankly, I discovered that as a UK citizen all you are entitled to is to live in the UK. That pretty much concludes it. Now, obviously you can move back to the UK and eventually regain some of the social services available to UK citizens that reside in the UK. The first thing you should do is apply for a NHS card upon arrival. However, bear in mind that your application might be rejected as you have to prove that you've permanently moved to the UK. The next thing you may want to do (see my citation below) is to take the "habitual residence test". In all likelihood you'll fail this one a few times as you probably do not meet the residency criteria (since you lived outside the UK most of your life). However, eventually given enough time and signing up in a couple of clubs, getting a job, etc, you'll probably pass it and then be entitled to social services.
The NHS lists the benefits as those:
Attendance Allowance
Carer's Allowance
Child Benefit
Child Tax Credit
Disability Living Allowance
Housing Benefit
Income Support
Jobseeker's Allowance.
