All mantra goes to Him, the vidhis that require a Guru would shift to surrendering your workings into Shiva.
Essentially for example with jaap, there are points in which you do a pooja once you have done x amount of jaap (kind of like milestones), here you would normally let your Guru know that you have passed x milestone and they would help you do the pooja as the Guru is normally required here.
The Guru is a manifested reflection (pratibhimba) of Shiva, as Shiva is the Guru of all. This pratibhimba is the channel within the physical Guru (generated and churned within them through their own practices) that you as a student interact with. You are essentially interacting with Shiva through another.
If you have decided or are deciding that Shiva is your Guru, that you do not require Him to manifest through another, that you call Him to manifest within you:
This requires cleansing and sharpening of your Bhava.
With a physical Guru it's just easier to get advice on the human level, as you can directly ask oh how do I do x or y? Questions are simpler to answer in the human state. But this does not mean it's harder to receive answers and guidance; to receive Shiva as Guru actually opens you to get true advice and guidance, and well you begin to understand things that you soon realize a physical Guru could not teach you the way Shiva does. He is the Guru of all.
But this requires a different subset of skills that are distinct from interacting with a physical Guru. It is not normally recommended to go straight to Shiva being your Guru because of your own illusions and chaos.
Your mind can pretend to be something it is not. The muddiness makes it hard, so the mud of the mind must first come off, cleansed, through inner and outward acceptance of Shiva being your Guru in the first place and treating that with reverence. Connecting to your Guru, not just oh "Shiva is everpresent so like I can connect when I need to do only the milestones or if my sadhana requires a Guru present."
No, your bhava needs to be shaped and practiced with consistency, so you may allow that bhava to be an entry way into beng able to hit that space within, where Shiva sits to teach; normally this is the heart space, it is also easier if you awaken your heart space as the place where you sit and learn from your Guru.
Then you will see Shiva respond, in your own language, the ways you learn best, you will also find yourself developing certain abilities or habits that help you recieve clearly your Guru's guidance.
It is different from a physical human Guru, but once you have opened your heartspace and your mind, and reverently accepted Shiva as your Guru (which He never stopped being, He always has been. It is you who struggles to hear and connect in, within yourself.) He is there to guide you completely, you will realize that as you continue connecting in with honest intention to learn, to be better, to understand as a student desires, with your bhava.
Sometimes things won't make sense but then suddenly they will, He takes you through your mind, clearing and churning the mind ocean so that it may become a garden of learning and teaching, as the heartspace blossoms as the resting and overall space of learning within.
Personifying Shiva through the mind is super useful as that imagination of Shiva is a reflection of Shiva Himself. Only Shiva could desire to be imagined by you, you can not imagine Shiva and it not be Shiva. It's accessing subjective reality. Your imagination allows you to access what you possibly could not ever imagine.
The imagination must also be given order, as it can spiral into chaos; therefore, inner work is naturally required and constant. So is grounding yourself.
The imagination allows you to create spaces within and access planes of inner reality.
The inner universe is vast.
Shiva as your Guru walks through it all with you, guiding your every step and thought.
Shaping you to be the most fulfilled and liberated you. Shaping you to embody your own truth.
