If your applications are:

Install LANSA on each IBM i server (if necessary), using a standard LANSA installation as described in the Installing LANSA on IBM i Guide.
Deploy your application using the standard export / import.

Create a custom install program that installs the LANSA run-time and your specific application components, including, potentially, non-LANSA components. To do this, you would make use of the silent install commands and guidelines in this guide.
 
To support a Silent Installation, LANSA delivers:
     LANSAINS, the equivalent of a typical LANSA on IBM i installation
     LANSAUPD, to update an existing deployment
     the LSI* Commands, a set of commands to support the custom installation, upgrade and modification of a LANSA system.
Examples of how to create QINSTAPP, an install program are also provided along with Guidelines for creating an installation Save file.
