Lot of stuff going on here.
the single quotes tell the shell to not perform parameter
interpretation. I think you will need double quotes and you will need
to tell sed that the stuff in the string is a sed script with the -e
flag.
sed -e "s/$1/$2/g" $3 >$3.tmp
Now I have not written too many functions in bash but I think you need a
name for your function, otherwise how can you call it?
function mysed () {
then you can call the function with the command mysed v1 v1 filename
Of course there is always the tr command.
