I don't think there's a 'right' answer, but generally speaking, this is the template I start with:
Start with plugins that won't modify the tone/sound, but help prepare the audio like:
- gain staging via Logic's built in track parameter, or a dedicated gain plugin
- noise gate (if needed)
- enveloper (sometimes I use a send for this so I can adjust the 'punch' on all my tracks)
- de-esser (vox only, this is so the processing done later with eq/comp gets a clean signal)
Then I move on to basic processing:
- virtual console (Slate Digital) to give it an analogue sound
- EQ/Compression (muck around with different ones, change the order and let your ears decide)
Then finally, any extras like:
- doubling, stereo spread, sonic enhancers etc.
I generally don't put any delay or reverb on the tracks themselves, I always use sends for those. What helped me the most was just using presets followed by a ton of experimenting...
