How do I redirect and interact with stderror

As an example not that it would work but say

mkdir -p ${ZDIR}${BIND_DIR} 2>&1 | tee -a $ZLOG || exit 1

The above isn't going to work as stdout/stderr is already redirected but always get confused here with how and the format of redirection. Is there a oneliner or if/fi where stdout/stderr can be redirected to a log file whilst if not successful can end with a exit or return 1?

Doesn't have to have the tee to screen can just be straight redirect to file. I always struggle with the bash format and struggling for an example with redirection and interaction.

mkdir -p "${ZDIR}${BIND_DIR}" 2>"$ZLOG" || exit 1

2>"$ZLOG": stderr is redirected to $ZLOG.
|| exit 1: if the command exits with a non-zero value, exit with 1.
