What type of Aura am I able to detect if my deity's alignment is true Neutral? Not sure how this aura ability work. If my deity was good then I could detect evil like a Paladin?
Aura (Ex)
A cleric of a chaotic, evil, good, or lawful deity has a particularly powerful aura corresponding to the deity’s alignment (see detect evil for details).

It means you give off that kind of aura. Generally, most people, good or evil, don't detect as good or evil unless they are higher level. Outsiders, like angels or devils do. Clerics and paladins have stonger auras and detect much more readily.
You can likely find the chart under the detect evil spell.
