Just use '\t' instead of ' ' in your log_format.
For example:
log_format tabbed '$remote_addr\t-\t$remote_user\t[$time_local]\t"$request"';

By default, rsyslog convert control characters to their ASCII values (#011 in case
of Tab). You may prevent this behavior by setting $EscapeControlCharactersOnReceive
to off.
