A lot of it is getting into routine - I have always had a routine of bags packed, coat and shoes ready at the door and uniform ready the night before so now it's something DD just does automatically.
When she gets home from school the first things she does is take off her shoes and coat at the door so they're ready for the morning then takes her bag to her room and changes out of her uniform and it gets hung on a hook on the back of her door. That way in the morning she just needs a fresh shirt from the wardrobe and everything else is in one spot to throw on, she's not running round the house trying to find her tie or tights when we need to leave in 2 minutes.
I let DD organise her own workload and prioritise the stuff that needs to be in soonest but otherwise I leave her to it and she does some homework every day. She usually does her homework at her desk in her room but sometimes comes and works at my desk in the living room if she wants some company but, regardless of where she works, when she's finished she brings her bag down to put in the hall unit and if it came out of her school bag then it goes back in her school bag (unless it's a work in progress/project that she doesn't need for the following day)
We have hooks for coats and then a 2x3 cube unit at the door with a side each - bags just sit on the top, one cube has baskets for hats/gloves/sunglasses/umbrellas etc; bottom cube is for shoes and then my other cube is used for anything I have to remember to take with me - library books to return, letters to post, things to drop off for other people etc - and DDs is for her extra curricular stuff - her flute and music books; the work books for her extracurricular language class; ballet and tap shoes for her dance classes - ready for the morning. If she needs anything for the following day - dance stuff, music stuff etc - then it's already there, the only things she has to actively remember are her PE and swim bags, but they live in a specific place in her bedroom and are always repacked immediately after the stuff is washed so, again, easy to just grab and go. Because everything has a specific home it's really easy to see if something is missing and I can remind DD "Did you bring your school bag out of your room?" because I can see the gap where it should be with just a quick glance at the unit.
It sounds like a lot and very regimented when it's written down but we don't even think about it, it's just automatic and takes seconds but makes life a million times easier in the mornings.
