You really should take more care of servers :)

What does Debian miss that you need for your servers (I am really interested).

Also for quick and dirty you could use checkinstall.

There is also a good tutorial on DigitalOcean about fpm:

And just maybe me nitpicking too much but the title should be then "How to quickly create deb package for personal needs". Notice that this means you don't get Debian Security support for your own package so that can be a huge breaker for many people running servers :)
