Here's one I'm familiar with:

https://autismspectrumnews.org/strengthening-community-engagement-with-vocational-training-and-employment-for-young-adults-with-autism/

Here's an important clip from the website:

Vocational skill training can help those with autism learn how to follow directions, improve motor coordination, and increase consistency, reliability and concentration. The focus should be on teaching social and functional skills that can transfer from one environment to another. Employment requires a repertoire of soft (social) and hard (job-related) skills. Soft skills include initiating and responding to greetings, conversation skills, responding to social situations, following directions, practicing good hygiene, time management, and dressing appropriately.

I'd suggest most if not all of the methods used to teach skills for young adults are also pretty much effective with older adults. The learning curve might be a little different, but that's true for anybody.

Best wishes!

Best wishes to you too.
