Timer circuit for led

How to make a simple circuit. This needs to fit inside of a cylinder about the size of an ink pen. Powered by a dc battery, (inside the cylinder) when voltage is applied, via a push button switch or a thurmail sensor, that starts timer/delay preset for 60 seconds then lights the led.
