anishsane's comment is right. Use a config file!

But just in case here is expect script that automates the entering of your data:

#!/usr/bin/expect

spawn vpnc

expect "Enter IPSec gateway address;"
send "yourdata\r";

expect "Enter IPSec ID for"
send "yourdata\r";

expect "Enter IPSec secret for"
send "yourdata\r";

expect "Enter username for"
send "yourdata\r";

expect "Enter password for"
send "yourdata\r";

And you can make it smaller if you pass most of your data as command line arguments as suggested by Jonathan:

#!/usr/bin/expect

spawn vpnc --gateway yourgateway --id yourid --username yourusername

expect "Enter IPSec secret for"
send "yourdata\r";

expect "Enter password for"
send "yourdata\r";

But as already mentioned, it is not the way to go. Use a config file instead.
