Not able to see Lead Data in Email Template on passing recordId to template from Apex Class

Here is what i have done...

Messaging.SendEmailResult[] results;
Messaging.SingleEmailMessage message = new Messaging.SingleEmailMessage();
message.setToAddresses(new String[] {ldOwnerMail});
message.setTemplateId([select id from EmailTemplate where DeveloperName='LeadsNewassignmentnotificationSAMPLE'].id);
message.setTargetObjectId(lead.OwnerId);
message.setSaveAsActivity(false);
results = Messaging.sendEmail(new Messaging.SingleEmailMessage[]{message});

How to pass recordId here so Emailtemplate can take it and show further details (Name,Company).

Template is look alike is--

** NEW LEAD STATUS CHANGE NOTIFICATION ***
The following lead's status has been changed.
Lead Name: {!Lead.Name}
Company: {!Lead.Company}
Here is the Lead Detail: {!Lead.Link}
