If you closed your Paypal account, the recurring transaction has been already cancelled.
If you still have the Paypal account and the recurring transaction is active then due to the fact that your CC has been discontinued, Paypal will not be able to obtain any money from it and your subscription will end at the date that it expires.
After that should you wish to renew it you will have to click the subscribe button at the top left and follow the prompts on the screen.
