You need to generate dynamic SQL Statements.

Mandatory BIG warning : do read up on "SQL Injection" (search on Google) before you proceed if you are using dynamic SQL with user input, but it does not look like the case here.

Something like this:

create proc mySP
@tablename sysname
as
declare @sql nvarchar(max)
set @sql = 'delete ' + @tablename -- everything
exec (@sql)
set @sql = 'insert into ' + @tablename + ' (col) values (val)'
exec (@sql)
