My plotting consists of writing down the big scenes that I need to get to and keeping notes on where my character development is at each part of the story.
For character development - With Wren, I've been sticking to Maslow's hierarchy of needs. He's currently working on the top two tiers, but still struggling with the occasional doubt as to the stability of the bottom tiers.
Jackson is already at the Self-Actualization stage, so at this point his character development happens when he's put in the same dorm as scholarship students as opposed to the rich boy dorms. Different experiences are what will push him into changing while Wren is still working on developing into himself.
I also keep track of my romance arc with the help of 'Romancing the Beat' by Gwen Hayes. Though I've edited her formula to fit my own writing style.
I have bullet points on my MC's backstory, what they want, etc.
So using The Love of a Werewolf as an example -
Big Plot Points
Wren and Jackson meet
Wren agrees to help free werewolves
Wren and Jackson meet Liam and Zain at school
Etc
Sometimes I have a long list of bullet points, sometimes I only have a couple. It depends on how plot heavy my novel is. If I'm writing just a romance, then I just mark down my main romance points and let the characters develop as I go. With TLoaW, there's a pretty heavy liberation plot going on so I had a lot more notes on points that I needed to hit.
With The Ghost of Summerside Cemetery,
Plot points
MC runs away from shitty home
He finds a job as a cemetery groundskeeper.
Haunted statue
Etc
Keeping my plot points small allows me to fill in the rest as I write. The specifics behind his bad home life are in his character bullet pointed list.
I don't know if this helped at all? It's what helps me so ymmv
I will say the best way to find out what works for you is to keep trying different ways of plotting. It's taken me years to find my preferred method of plotting and knowing when to write!
