If you want to set the mask for the home directory created adjust
DIR_MASK in /etc/adduser.conf
If you want all files the user created with 700 add
umask 0007
to ~/.profile
or for all new users created to /etc/skel/.profile

A check if the user is a regular user might be usefull. Some system
tools/daemons might not work like expected when the umask is changed.
Normal users are created with in a uid between 1000 and 29999 on debian
systems.
So something like:

ID=`id -u -r`
if ((1000<=$ID && $ID<=29999)
 then umask 0007
fi
unset ID

Will change the umask only if the real id is between 1000 and 29999.
