Adjust the potentiometer to get an output voltage between 1.27 and 12.6 volts. 
I haven't tried it on the breadboard yet so I don't know if it works properly, but it seems fine here with ideal components. 
The circuit works with a BJT as the pass transistor as well. A base resistor would not be required since the op amp would take care of supplying the right amount of base current.

Nice circuit, please spend a bit more time on the layout; http://everycircuit.com/circuit/5507731843448832

I chose this layout cause it looks compact, but you layout is also quite neat. It's personal preference, really. But don't get me wrong, i do think that a proper layout is important.

On second thoughts, your layout is better

Looks good, but you should add stabilisation.

Why did you remove the cap from the non inverting terminal?

No reason - it works with or without it.
