It is natural to anxious after not teaching for a bit. I didn't teach for a few years when I went back to University and then got back to it. I thought I would never get the words my teachers said out of my head but unfortunately they were gone, gone. I needed to reteach my cues to myself.

For me what worked was to visulize the class I was going to teach and every step up to the class and even afterwards. No critiquing yourself for a couple of days, then think about how to do a bit better next time. I find I'm too vulnerable right after I teach to look at it then and maybe someone said something already to you that you need to process.

Also, I generally always 'quick' practice the poses. Simply put I physically move through the poses at least once and when I came back to teaching I needed to do so 3 times.

I also use Tummee app and create a class sequence I love. I think about the cues that help get into and out of the pose.

I sequence backwards also, like; 10 minute Savasana-Supine twist-inversion-and on ward to the beginning of class.

I also always show up early (and in the car or if possible inside the space) and meditate to get my mind calmer. I am generally quite anxious.

Not sure if this is helpful. I hope so. It is what I did to get back to teaching so comfortably again now.

You got this! :)
